20- to 40-year sentence in Chester County road-rage killing

A Trainer man who shot and killed a teenager in a road-rage incident on a Chester County highway was sentenced Thursday to 20 to 40 years in state prison, the statutory maximum for third-degree murder, in an emotional hearing that brought even the judge to tears.

After hearing heartbreaking testimonies from Roberson’s family and friends, and remorseful words from Desper, Chester County Court Judge Ann Marie Wheatcraft wept as she handed down her sentence.

“Mr. and Mrs. Roberson, the criminal justice system is completely inadequate as a means of healing,” she said. “Mr. Desper, you took Bianca’s life and future from her. ... It is my duty to deprive you of your liberty for a significant period of time.”

Shackled, and dressed in a purple shirt and striped tie, Desper hung his head and cried, his body shaking. Beside him, his attorney, Daniel McGarrigle, who had asked for a lesser sentence, shook his head.

In the front row of the packed gallery, Roberson’s mother, Michelle, reached for the hand of Roberson’s father, Rodney.

“I’m satisfied, a little bit. The family is somewhat relieved,” Roberson’s father said. “People make mistakes. But some mistakes you can’t come back from."

Through tears, Desper told the judge he wished more than anything that he could take back the split-second decision to pick up his .40-caliber Smith & Wesson semiautomatic pistol from on top of his truck’s center console and fire out his open window at the driver beside him on Route 100 southbound during the evening rush hour on Wednesday, June 28, 2017.

“I’d do anything to take it back,” he said, turning toward Roberson’s family and friends. “I really would. I’m so sorry.”

Rodney Roberson still wanted answers, particularly to one question: Why?

“Why in God’s name did you shoot my daughter?" he asked. “Because she was young? Because she was black? Because she was a girl? Because you wanted to be able to go first on the road? Because you had a bad day?”

Prosecutors have said Roberson was not driving recklessly, and Wheatcraft said she didn’t buy Desper’s account.

“I don’t believe you were afraid,” she said. “If you’re afraid when you’re driving, you hit the brakes. I believe you were angry.”

As Roberson’s car veered off the road, Desper fled home to Delaware County, then went on a beach trip with friends, where, prosecutors said, he played mini-golf, ate pancakes, and acted normally until confiding in friends and family about what had happened.

Desper’s mother, Wendy, said she received a call from her son just hours after she posted on Facebook about the manhunt for the “jerk who killed a high school graduate."

On the other end of the line, her son said, “I’m so sorry. I screwed up. I did something I can’t take back,” she said. Immediately, she said, she knew what he had done.

“He’s going to have a tough time living with this,” Wendy Desper said. “He truly is.”

McGarrigle, Desper’s attorney, said his client was a “harmless, almost juvenile" man who did not drink or do drugs, and had no criminal record before the killing. As authorities searched Desper’s bedroom last July, McGarrigle said, he noticed that Desper had plastic stars above his bed and Camaro posters on the wall.

“There is a certain cold comfort in seeking a monster because it helps us all sleep at night,” McGarrigle said. “But if we did that, the system would not be doing its job.”

But to prosecutors, and Roberson’s family and friends, Desper was just that — a threat to society who deserved nothing short of the maximum sentence, they said.

Rodney Roberson recalled memories of his “little girl,” whom he and his wife decided to raise in Chester County, not his native West Philadelphia, to keep her safe.

Even as his daughter grew up, got a job, and prepared for college, he worried about being able to protect her, he said. But all of his hopes for her were coming to fruition, he said, until she crossed paths with Desper.

Bianca Roberson loved to listen to Luther Vandross' “Dance With My Father" with her dad. Rodney Roberson said he would tell her that the song, a ballad about a man longing for his late father, was morbid. Now, he finds solace in it.

“Your honor, I would love to dance with my daughter again," he said, “but I never will.”

Michelle Roberson said her daughter lived to help others, always going out of her way for people who were struggling or alone.

“She would try to save the world from the ugliness we’re in,” she said, “and look, the ugliness took her.”

Bianca Roberson encountered Desper while driving home to West Chester from a shopping trip in Exton with her mother and grandmother.

Michelle Roberson said she wanted her daughter to head straight home that day. Unbeknownst to her daughter, she had been tracking a package of dorm bedding and decorations, and knew it would be in the driveway when her daughter returned.

Unwilling to give way to Roberson’s car, Desper grabbed his gun, the one a friend said Desper often kept in the center console, and fired a single shot. The bullet struck Roberson in the left side of the head, and her vehicle went off the road, eventually resting against a tree. The case was considered a traffic accident for a day, authorities said, until the coroner found the bullet in Roberson’s head.

As officials searched for Desper, he confided in a friend, telling the man “Whoa, I really ... up, man," according to documents read at a hearing in the spring.

Desper eventually turned himself in on July 2, allowing authorities to search his truck and his family’s Trainer home, where the gun was found. Since that day, Desper has been held at the Chester County Correctional Facility. He will now be transferred to a state prison.

He was originally set to go to trial in September, but instead he entered an open guilty plea, which means he was not promised a certain sentence. Prosecutors said they accepted a plea of third-degree murder because they worried that a jury might not believe that Desper intended to kill Roberson with that single shot.

McGarrigle argued Thursday that Desper should receive credit for turning himself in, helping authorities with the investigation, and sparing the Roberson family the pain of a trial by pleading guilty.

Wheatcraft did not tack on a consecutive one- to two-year sentence for possession of an instrument of crime, she said, because Desper pleaded guilty.

McGarrigle declined to comment after the sentencing and said he did not want to discuss whether he planned to appeal.
